Local code execution via untrusted pointer dereference
Published Jan 9, 2024 · Updated May 3, 2025
Untrusted pointer dereference in Microsoft Windows Cryptographic Services allows local users to execute code on affected systems. Microsoft identifies the weakness but has not disclosed the affected function, input path, or erroneous dereference operation. Low-privileged local access is sufficient and no user interaction is required; successful exploitation compromises data and system operation.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
